The Mets won tonight despite Terry Collins’ over-managing. They overcame a rocky start by Jacob deGrom to take a four-run lead into the ninth. Everything seemed to be falling in place for the Mets.

Addison Reed worked the eighth and got Justin Turner on an inning-ending double play. He needed only seven pitches, so there was no concern about him being overworked.

That’s when Collins started poking at embers on the grill.

“You can’t worry about tomorrow,’’ Collins inexplicably told reporters as to why he used Jeurys Familia in a non-save situation. “You want to win the game.’’

How many times can you remember the Mets expanding a lead and have Familia sit down and somebody else enter the game?

Collins said he’s used Familia in non-save situations before. Friday was the eighth time he’s done it. Sometimes a closer will be brought in that way if he hasn’t had a lot of work.

Including tonight, Familia has pitched five times in the past week and converted three save opportunities, so it’s not as if he needed the work.

Familia hasn’t been effective in that role and certainly was off Friday, giving up three straight singles and a bases-loaded walk to bring in one run. Collins could see Familia didn’t have it, but what was he going to do, pull his closer for somebody else to close the game?

Instead, he let him pitch to Chase Utley, who drilled a three-run double into the right-center gap. All that talk about retribution with Utley seems tired and moot right now.

Familia eventually got out of the inning – he struck out three – but needed a season-high 32 pitches to do so. It remains to be seen if Familia will be available Saturday.

Curtis Granderson homered down the right-field line off Pedro Baez on the second pitch he saw to take both Familia and Collins off the hook.

SUMMARY: Instead of his fourth victory, Jacob DeGrom came away with a no-decision when Familia couldn’t hold a four-run lead in the ninth. Granderson took a night of angst away from Familia and Collins by hitting his ninth homer.

KEY MOMENT: Granderson’s leadoff homer in the ninth.

THUMBS UP:DeGrom’s ability to pitch out of trouble, highlighted by a fastball in the mid-90s. It could have been his best fastball of the season. … David Wright homered for the third straight game. … No unnecessary fireworks involving Chase Utley. … Asdrubal Cabrera’s defense and guess what, he got another hit. … Two hits from Neil Walker.

THUMBS DOWN: Collins’ decision to go with Familia and the closer’s dismal performance (four runs on four hits and a walk). … Mets’ hitters struck out 12 times. … Granderson struck out three times and is now hitting .195. … Familia struggled in a non-save situation, giving up four runs in the ninth.

EXTRA INNINGS:GM Sandy Alderson said the team is still exploring external first-base options. Kelly Johnson and James Loney are being considered. … Eric Campbell started his fourth straight game at first. … Wilmer Flores is expected to return from the disabled list soon, perhaps during this series. He can play first. … The Mets discounted the idea of using Conforto at first. … Matt Harvey pitched to Alejandro De Aza and Matt Reynolds prior to the game as the team still is searching for answers. Harvey is scheduled to start Monday against the White Sox.

Matt Harvey has a chance to make it all better for him and the Mets Tuesday in Washington. Coming off arguably the worst start of his still short career, he gave up nine runs to the Nationals to generate the “what’s wrong with Harvey,’’ chatter.

The theories were endless, ranging to his heavy workload last year coming off Tommy John surgery and a light spring training to his health. Was he hurt? Was he trying to overcompensate for Game 5? What’s wrong with his velocity and mechanics?

Now, after the Mets ripped the Nationals, 7-1, Monday, Harvey will get the ball with the chance to pitch the Mets back into first place.

It’s only May and with so much of the season left the standings aren’t of paramount importance. However, it is not a stretch to say outside his first game back from Tommy John surgery, this could be the most important regular-season start of his career.

Manager Terry Collins, believing Harvey’s confidence could be rattled, gave him the option of skipping this start. Sometimes to his detriment, Harvey always wants the ball, so there was no chance that would happen.

None.

“Obviously, it’s frustrating being out there right now when you’re not doing well and not helping the team,” Harvey told ESPN.com. “As a teammate, your objective is to do everything you can to win games and help us succeed.

“And I wasn’t doing that. So, obviously, they gave me an option to be skipped or whatnot and really try to figure things out. For me, taking time off isn’t going to do anything. It’s finding it on the mound.

“I’m not a quitter. I’m not going to just quit and put the ball down. It’s a fight. It was good for me to do that.”

Harvey has issues, but nobody can accuse him of being a quitter.

The easy thing would have been for Harvey to decompress on the bench, but he knows that wouldn’t have been the right choice. There would be the inevitable speculation as to whether he is physically sound.

Even worse, his competitive nature would have been questioned. Can you imagine the storm if Harvey sat Tuesday and the Mets went in a tailspin?

Pitching was Harvey’s only choice.

If he puts it together and goes on a productive run, all of this will go down as another blip on the Mets’ radar screen.

THUMBS UP: Colon was on the ropes in the first, but with runners on first and second he got Anthony Rendon on a fly to left. Who thought Colon would have gone out for the seventh? … Cespedes hit his 15th homer and Walker his 11th. … Two hits each from Curtis Granderson, Juan Lagares, Cespedes, Walker and Asdrubal Cabrera. … More solid work from the bullpen.

THUMBS DOWN: Just a short rain delay. … Lucas Duda went on the disabled list and could be gone for up to six weeks. … In a blowout, it would have been nice to see Ty Kelly.

QUOTEBOOK: “There’s no real timetable. It’ll be awhile. I guess there are some exercises he can do, but nothing baseball related for awhile. We’re looking at a fairly long period.’’ – Collins on Duda’s injury.

BY THE NUMBERS: 63: Mets homers to lead the NL. They are third in the majors.

NEXT FOR METS: Matt Harvey takes the ball – and a myriad of concerns and worries – to the mound against Stephen Strasburg.

Bartolo Colon gets another shot at the Nationals tonight in DC. He was hammered by Washington in his last start, giving up three runs on five hits and five walks in 4.2 innings. The five walks Colon (3-3, 3.75) were the most he’s given up in a game since 2005.

As you know by now, Lucas Duda was placed on the disabled list this afternoon.

Bartolo Colon – RHP: Career vs. Nats: Is 3-6 with a 3.38 ERA lifetime against the Nationals in 10 games, including nine starts. Has 14 wins vs. NL East since the start of the 2015 season.

COMMENTS: Conforto is getting hot again, so I’d hate to sit him. Five of his eight homers have either tied the game or given the Mets the lead. … Mets pitchers have 10 no-walk games to lead the majors. … Jeurys Familia has converted 31 consecutive save opportunities to tie him with Billy Wagner for the club record. … The Mets’ bullpen has thrown 14.1 scoreless innings over the last four games. … The Mets were 6-3 against the Nationals last year in Washington.

As speculated here yesterday, the Mets placed first baseman Lucas Duda on the 15-day disabled list, retroactive to May 21, with a stress fractured to his lower back. Taking Duda’s spot on the roster is Ty Kelly from Triple-A Las Vegas.

Kelly can play both the infield and outfield and is available for tonight’s game in Washington. To make room on the 40-man roster lefty reliever Dario Alvarez was designated for assignment.

Kelly, 27, was signed as a minor league free agent, last November. He is leading minor league baseball with a .391 average and an on-base percentage of .478. He was previously in the Baltimore, Toronto and St. Louis organizations. He was originally drafted by the Orioles in the 13th round in 2009.
